What this skill tells the agent
[RALPH - ITERATION {{ITERATION}}/{{MAX}}]
Your previous attempt did not output the completion promise. Continue working on the task.
<Purpose> Ralph is a PRD-driven persistence loop that keeps working on a task until ALL user stories in prd.json have passes: true and are reviewer-verified. It combines session persistence, automatic retry on failure, structured story tracking, and mandatory verification before completion. </Purpose>
<Use_When>
- Task requires guaranteed completion with verification (not just "do your best")
- User says "ralph", "don't stop", "must complete", "finish this", or "keep going until done"
- Work may span multiple iterations and needs persistence across retries
- Task benefits from structured PRD-driven execution with reviewer sign-off </Use_When>
<Do_Not_Use_When>
- User wants a full autonomous pipeline from idea to code -- use
autopilotinstead - User wants to explore or plan before committing -- use
planskill instead - User wants a quick one-shot fix -- delegate directly to an executor agent
- User wants manual control over completion -- delegate directly to an executor agent
- User already has an active Claude Code
/goaland only wants that native goal loop monitored -- adopt the existing/goalexplicitly or use artifact-only Ultragoal notes instead of starting Ralph as a competing persistence loop </Do_Not_Use_When>
<Why_This_Exists> Complex tasks often fail silently: partial implementations get declared "done", tests get skipped, edge cases get forgotten. Ralph prevents this by:
- Structuring work into discrete user stories with testable acceptance criteria (prd.json)
- Iterating story-by-story until each one passes
- Tracking progress and learnings across iterations (progress.txt)
- Requiring fresh reviewer verification against specific acceptance criteria before completion </Why_This_Exists>
<PRD_Mode> By default, ralph operates in PRD mode. A scaffold prd.json is auto-generated when ralph starts if none exists. Active transient PRD state is session-scoped at .omc/state/sessions/{sessionId}/prd.json when a session ID is available; legacy project-level prd.json / .omc/prd.json files are read as startup migration inputs.
Startup gate: Ralph always initializes and validates prd.json at startup. Legacy --no-prd text is sanitized from the prompt for backward compatibility, but it no longer bypasses PRD creation or validation.
Deslop opt-out: If {{PROMPT}} contains --no-deslop, skip the mandatory post-review deslop pass entirely. Use this only when the cleanup pass is intentionally out of scope for the run.
Reviewer selection: Pass --critic=architect, --critic=critic, or --critic=codex in the Ralph prompt to choose the completion reviewer for that run. architect remains the default.
Stale-state detection & reconciliation (#3669): If a PRD is left unfinished by an abnormal/non-Step 8 exit (crash, force-kill, cancel before /oh-my-claudecode:cancel, session end), Ralph surfaces an explicit [STALE PRD WARNING] at startup/resume, in the continuation context, and at session end — with unfinished counts, last-touched age, and stale-pointer signals (PRD branchName merged/gone). Completion is NEVER inferred from PR/branch/merge status alone; git state is a warning signal only. A story is auto-reconciled to passes: true ONLY when the PRD carries configured observable evidence and every check passes:
{
"reconciliation": {
"staleAfterMs": 7200000,
"observableChecks": {
"US-001": [
{ "type": "fileContains", "path": "src/landed.ts", "pattern": "LANDED_SYMBOL" },
{ "type": "gitGrep", "ref": "origin/dev", "pattern": "LANDED_SYMBOL" }
]
}
}
}Check types: fileExists / fileContains (working tree) and gitGrep (content at a ref — this is "verified by content on trunk", never PR status). Stories without configured checks are never auto-marked. Reconciled stories keep architectVerified: false and still require Step 7 reviewer verification before Step 8; every decision is appended to the prd-reconciliation.jsonl audit log and summarized in the story notes. </PRD_Mode>
<PRD_Criterion_Amendments> Acceptance criteria are the PRD's completion authority: Step 4 verifies EACH active criterion and Step 7 reviews against them. A criterion can stop governing ONLY through the evidence-preserving amendment path — never by silent deletion or by "satisfying" a criterion measurement has refuted.
When implementation proves a criterion empirically false (e.g. a count in the dispatching brief is wrong), amend it:
- Replace the refuted criterion with the measured correction, or supersede it when no replacement governs.
- Record the amendment in the story's
criterionAmendmentsledger. The original criterion text is retained verbatim (never rewritten or deleted) alongside:
kind:"replaced"or"superseded"original: the verbatim refuted criterion (must still be active when the amendment is recorded)replacement: the corrected criterion (only forreplaced)reason: why the original no longer governsevidence: the bounded measurement that refuted it (e.g. "enumerated 12 setters, not 16: ...")authority: who made the amendment (use the ralph session id)timestamp: ISO 8601 timestamp
- The completion check then verifies only the ACTIVE criteria; the ledger keeps the audit trail so reviewers see why the original no longer governs.
Rules:
- An amendment without bounded evidence, reason, authority, or timestamp is invalid — the PRD fails closed on read rather than being silently weakened.
- An original that is still active cannot be amended; an original can be amended only once.
- Programmatic path:
amendCriterion(dir, storyId, { original, replacement, reason, evidence, authority })andsupersedeCriterion(dir, storyId, { original, reason, evidence, authority }). - Hand-edited PRDs must preserve the same invariants; a contradictory ledger (original still active, or amended twice) makes the PRD invalid.
- This is not a goal-weakening tool: it exists so that "the measurement disagrees with the plan" resolves toward the measurement without the loop losing its grip.
</PRD_Criterion_Amendments>
<Execution_Policy>
- Fire independent agent calls simultaneously -- never wait sequentially for independent work
- Use
run_in_background: truefor long operations (installs, builds, test suites) - Always pass the
modelparameter explicitly when delegating to agents - Read
docs/shared/agent-tiers.mdbefore first delegation to select correct agent tiers - Deliver the full implementation: no scope reduction, no partial completion, no deleting tests to make them pass
- If a Claude Code
/goalis mentioned, treat it as a native session-loop handoff/evidence source only and use the deterministic conflict policiesrefuse,adopt_existing, andartifact_onlyrather than non-deterministic warning handling. Ralph remains the OMC loop authority for this run; do not claim/goalindependently ran tests or read files, and do not treat evaluator success as a substitute for Ralph reviewer verification. </Execution_Policy>
<Steps>
- PRD Setup (first iteration only): a. Check the active PRD file surfaced in the Ralph continuation context. In session-scoped runs this is
.omc/state/sessions/{sessionId}/prd.json; legacy project-levelprd.json/.omc/prd.jsonfiles may be copied there at startup for backward compatibility. b. If no legacy PRD exists, the system has auto-generated a scaffold at the active PRD path. c. CRITICAL: Refine the scaffold. The auto-generated PRD has generic acceptance criteria ("Implementation is complete", etc.). You MUST replace these with task-specific criteria:
- Analyze the original task and break it into right-sized user stories (each completable in one iteration)
